Technical Field

[0001] This invention discloses a stamping and forming device for anti-loosening nuts, belonging to the field of fastener production technology. Background Technology

[0002] Locknuts are a common type of mechanical fastener. They prevent the nut from loosening under vibration by using an anti-loosening plate inside the nut, where the curved part of the anti-loosening plate elastically abuts against the bolt thread. In existing technology, the forming of locknuts typically requires multiple independent processes: first, machining the nut body; then, separately punching out the anti-loosening plate; and finally, fixing the anti-loosening plate to the ring within the nut body by riveting or welding. This step-by-step processing method suffers from problems such as fragmented processes, low automation, low production efficiency, and difficulty in ensuring product consistency.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] like Figures 1-10 As shown, a stamping and forming device for anti-loosening nuts includes: A stamping assembly is used to punch out anti-loosening pieces 2 with through holes 5 and arc-shaped parts 4 from a metal sheet 6. The stamping assembly includes a moving die 12, a fixed die 14, a first punch 7, a second punch 9, a first die 43, and a second die 19. The first punch 7 and the second punch 9 are fixed on the moving die 12 in sequence. The first die 43 and the second die 19 are both fixed on the fixed die 14, and they are located below the first punch 7 and the second punch 9, respectively. The feeding assembly includes a first turntable 18 and a second turntable 16. Both the first turntable 18 and the second turntable 16 are provided with a plurality of positioning holes 30 for positioning the nut body 1. The first turntable 18 is used to receive the punched anti-loosening plate 2 and put it into the ring plate 3 of the nut body 1. The second turntable 16 is used to place the nut body 1 containing the anti-loosening plate 2 and transport it to the bottom of the forming assembly. A forming assembly is used to rivet the ring 3 to deform it into an anti-loosening structure that prevents the anti-loosening piece 2 from detaching from the nut body 1. The forming assembly includes a third punch 11, a movable sleeve 22, a first limiting bolt 44, and a first spring 45. The third punch 11 is fixed on the moving mold 12. One end of the first limiting bolt 44 passes through the movable sleeve 22 and is fixedly connected to the fixed mold 14. The first spring 45 is sleeved on the first limiting bolt 44 and applies a force to the movable sleeve 22 against the fixed mold 14. One end of the movable sleeve 22 has a countersunk hole 23 that mates with the third punch 11, and the other end has a forming part 46. The mold frame 15 is used to install the stamping assembly and the feeding assembly, and the mold frame 15 is also provided with a power component 8 for driving the fixed mold 14 to move vertically. The power component 8 is a cylinder, a hydraulic cylinder or an electric telescopic rod. The transmission component 10 is connected to the fixed mold 14, the first turntable 18 and the second turntable 16, and is used to drive the first turntable 18 and the second turntable 16 to perform intermittent movements with opposite directions and equal angles when the fixed mold 14 reciprocates vertically.

[0018] The mold frame 15 is provided with a waste discharge hole below the first die 43. The second die 19 has a cylindrical guide part to guide the anti-loosening piece 2 to fall accurately into the ring 3 of the nut body 1. The waste material generated by punching the metal sheet 6 is driven by the first punch 7 to pass through the first die 43 and enter the waste discharge hole. The guide part allows the punched anti-loosening piece 2 to fall smoothly into the ring 3 under the drive of the second punch 9, and finally flatten the anti-loosening piece 2 on the nut body 1 for subsequent riveting processing.

[0019] The first turntable 18 is higher than the second turntable 16, and the horizontal projections of the positioning holes 30 of the two coincide at a certain rotation angle, so that the nut body 1 falls from the first turntable 18 into the second turntable 16 by gravity. This structural design allows the nut body 1 to fall automatically, which facilitates the subsequent feeding of material on the first turntable 18, and also allows the nut body 1 on the second turntable 16 to rotate to the bottom of the forming component for riveting processing.

[0020] The transmission assembly 10 includes a drive block 28, a sliding seat 29, a one-way clutch 20, and a damping element 21. The moving mold 12 is provided with a second limiting bolt 26 and a second spring 27 for mounting the drive block 28. The second limiting bolt 26 passes through the moving mold 12 and connects to the drive block 28. The second spring 27 is sleeved on the outside of the second limiting bolt 26 and applies a force to the drive block 28 away from the moving mold 12. The sliding seat 29 is horizontally slidably disposed within the mold frame 15, and a mutually cooperating inclined T-block 31 and inclined trapezoidal groove are provided between the sliding seat 29 and the drive block 28. Multiple toothed blocks 32 are provided on both sides of the sliding seat 29. Two one-way clutches 20 are provided, and their power input ends are provided with gears 33. A fixed shaft connects the power output end to the first turntable 18 and the second turntable 16. The damping element 21 is mounted on the mold frame 15 and is used to apply resistance to the rotation of the first turntable 18 and the second turntable 16. The one-way clutch 20… The device includes a rotating seat 42, a fixed seat 35, a driving seat 34, an annular frame 41, a pressing column 37, and a pressing member 36. The rotating seat 42 and the gear 33 are integrally formed. The driving seat 34 and the annular frame 41 are located between the rotating seat 42 and the fixed seat 35. The outer side of the driving seat 34 is provided with a pressing slope 38. The distances from the two ends of the pressing slope 38 to the side wall of the fixed seat 35 are not equal. The annular frame 41 is located on the outer side of the driving seat 34 and has multiple cutouts for installing the pressing column 37. The two ends of the pressing member 36 are connected to the driving seat 34 and the pressing column 37, respectively. The pressing member 36 applies a force to the pressing column 37 at the position where the pressing slope 38 is at the minimum distance between the side wall of the fixed seat 35 and the pressing surface 38. The pressing member 36 includes a third spring 39 and a movable rod 40. The movable rod 40 is a telescopic rod structure, and its two ends are rotatably set with the driving seat 34 and the pressing column 37, respectively. The third spring 39 is sleeved on the movable rod 40.

[0021] When the power component 8 drives the moving mold 12 to descend, the drive block 28 moves synchronously with the moving mold 12. Relying on the cooperation between the inclined T-block 31 and the inclined ladder groove, the sliding seat 29 slides horizontally, driving the two gears 33 to rotate in opposite directions. Figure 8As shown, gear 33 can drive drive seat 34 to rotate, causing extrusion inclined surface 38 to move relative to pressing column 37, and pressing column 37 to press tightly against drive seat 34 and fixed seat 35, thus smoothly driving first turntable 18 and second turntable 16 to rotate a certain angle. Then sliding seat 29 abuts against mold frame 15 and cannot move further. Due to the presence of second spring 27, power component 8 can continue to drive moving mold 12 to descend, allowing second punch 9 to drive anti-loosening plate 2 into ring plate 3 and be pressed onto nut body 1. At the same time, third punch 11 can drive movable sleeve 22 to rivet ring plate 3. When power component 8 drives moving mold 12 to move upward, drive block 28 remains stationary under the action of second spring 27 until one end of second limit bolt 26 abuts against moving mold 12. Moving mold 12 drives drive block through second limit bolt 26. 28 moves upward and resets the sliding seat 29. At this time, the sliding seat 29 drives the two gears 33 to rotate. When the gears 33 drive the extrusion inclined surface 38 on the drive seat 34 to move, it slips against the pressing column 37, so the power on the rotating seat 42 cannot be transmitted to the fixed seat 35, and thus cannot drive the first turntable 18 and the second turntable 16 to rotate. Under the action of the pressing member 36, the pressing column 37 in the one-way clutch 20 always abuts against the minimum distance between the extrusion inclined surface 38 and the side wall of the fixed seat 35. In this way, when the rotating seat 42 needs to transmit power to the first turntable 18 and the second turntable 16, there will be no delay. Thus, the rotation angle of the first turntable 18 and the second turntable 16 can be precisely controlled by controlling the sliding distance of the sliding seat 29 and the transmission ratio between the toothed block 32 and the gear 33, so as to smoothly stamp and form the anti-loosening nut.

[0022] The mold frame 15 is provided with a mounting groove for mounting the damping element 21. The damping element 21 includes a fourth spring 24 and a movable block 25. A hemispherical protrusion is provided on one side of the movable block 25. The first turntable 18 and the second turntable 16 are provided with grooves that cooperate with the hemispherical protrusion. The fourth spring 24 applies an abutment to the first turntable 18 and the second turntable 16 against the movable block 25. The number of grooves is the same as the number of positioning holes 30. When the first turntable 18 and the second turntable 16 rotate, when the hemispherical protrusion slides out of alignment with the groove, a certain amount of force is required. When the power component 8 drives the moving mold 12 and the drive block 28 to descend, the sliding seat 29 drives the gear 33 to rotate. The first turntable 18 and the second turntable 16 can be smoothly driven to rotate by the pressure column 37, and the resistance of the damping component 21 can be overcome. However, when the power component 8 drives the moving mold 12 and the drive block 28 to rise, the sliding seat 29 drives the gear 33 to rotate in the opposite direction. At this time, the pressure column 37 is in a slipping state between the drive seat 34 and the fixed seat 35. It cannot overcome the resistance of the damping component 21 and drive the first turntable 18 and the second turntable 16 to rotate.

[0023] The mold frame 15 has a notch 17 above the first turntable 18 and the second turntable 16, and a dropping hole is provided below the second turntable 16. The notch 17 can conveniently place the nut body 1 into the positioning hole 30 of the first turntable 18, and can also observe whether the anti-loosening nut in the positioning hole 30 on the second turntable 16 falls smoothly from the dropping hole.

[0024] The mold frame 15 is also provided with a guide post 13 that slides with the moving mold 12. The guide post 13 can guide the vertical movement of the moving mold 12, thereby ensuring that the punch and die cooperate to realize punching, blanking and riveting.

[0025] Working principle: The metal sheet 6 is intermittently conveyed on the fixed mold 14. In order to ensure that the anti-loosening piece 2 enters the ring piece 3 smoothly and is subsequently riveted, the distance between the positioning hole 30 indicated by arrow X1 in the first turntable 18 and the positioning hole 30 indicated by arrow X2 in the second turntable 16 is an integer multiple of the intermittent conveying distance of the metal sheet 6. Then, the moving mold 12 moves downward under the drive of the power component 8. The first punch 7 punches out the through hole 5 of the anti-loosening piece 2 on the metal sheet 6. The waste material falls from the waste discharge hole after passing through the first die 43. Then, the metal sheet 6 steps to the bottom of the second punch 9. The moving mold 12 presses down again. The second punch 9 and the second die 19 cooperate to punch out the anti-loosening piece 2. The anti-loosening piece 2 moves downward along the guide part of the second die 19 under the push of the second punch 9.

[0026] The operator places the nut body 1 into the positioning hole 30 on the first turntable 18. The first turntable 18 rotates intermittently. When the positioning hole 30 carrying the nut body 1 rotates to directly below the guide section, the punched anti-loosening piece 2 falls into the ring piece 3 of the nut body 1. The first turntable 18 continues to rotate. When the nut body 1 rotates to a position that coincides with the projection of the positioning hole 30 on the second turntable 16, the nut body 1 automatically falls into the positioning hole 30 on the second turntable 16 by gravity. Subsequently, the second turntable 16 drives the nut body 1 to rotate directly below the forming assembly.

[0027] When the nut body 1 with the anti-loosening plate 2 is located directly below the forming assembly, the moving mold 12 drives the third punch 11 to move downward. The third punch 11 passes through the gap on the fixed mold 14 and enters the countersunk hole 23 of the movable sleeve 22, pushing the movable sleeve 22 to compress the first spring 45 and move downward. The forming part 46 at the end of the movable sleeve 22 rivets the ring plate 3 of the nut body 1, causing the ring plate 3 to undergo plastic deformation, and finally forming a limiting structure with a semi-circular cross-section, which firmly restricts the anti-loosening plate 2 inside the nut body 1. After the riveting is completed, the moving mold 12 rises, the first spring 45 returns to its original position, the movable sleeve 22 disengages from the anti-loosening nut, and then the second turntable 16 drives the anti-loosening nut to rotate, causing it to fall automatically from the dropping hole.
